NOTES:
Flow Rate is based on 5 GPM per cubic foot at 6 lbs of salt per cubic foot per regeneration for greater than 90% hardness removal.
Reduce Flow Rate to 3.5 GPM per cubic foot at 10 to 12 lbs of salt per cubic foot per regeneration for 100% hardness removal (Service Flow Rate x 0.7).
Peak Flow Rate: (Service Flow Rate x 2.0).
